Create on the RA console a new scan task. The first window, edit the scan task options and enabled everything. Scanning in archives, scanning in e-mail, et al. In the cleanup options there are probably 20 different things to configure. What to do with e-mail, what to do with memory infections. Modify each of these to delete with the quarantine checkbox.

That works for me. You can create a custom scan profile with all the options, push it to all your clients, and then specify to use that for cleanup scans so you don't have to keep setting up these settings. Just make sure to push it to new clients too.
